Spinach and Mushroom Quiche with Shiitake Mushrooms

Step 1
Preheat the oven to 375 degrees F (190 degrees C).

Step 2
Fit pie crust into a 9-inch pie dish.

Step 3
Melt butter in a large skillet over medium heat; cook and stir green onions and garlic until green onions are softened, about 5 minutes. Cook and stir turkey bacon in green onion mixture until fragrant.

Step 4
Stir spinach, shiitake mushrooms, and broccoli into green onion mixture; cook and stir vegetables until softened, 5 to 7 minutes. Mix in 1/4 cup Cheddar cheese.

Step 5
Spoon vegetable mixture into pie crust.

Step 6
Beat eggs, milk, sea salt, and black pepper together in a bowl; pour egg mixture gently over vegetable filling, slightly stirring eggs into filling to combine.

Step 7
Bake in the preheated oven for 15 minutes; sprinkle 1/2 cup Cheddar cheese over the top of quiche and bake 10 additional minutes. Cover quiche with aluminum foil and bake until quiche has set and a toothpick inserted into it comes out clean, about 10 more minutes.

Step 8
Allow quiche to cool for 5 minutes before serving.
